With a recent study revealing that as many as one-in-four young British women are now teetotal.
General manager Angus Mackay decided to take advantage of the trend that showed that more and more young Britons are choosing to go teetotal.
He hit upon the idea after noticing that several high-profile celebrities have decided on tee-total stag dos recently, including Dermot O'Leary and James Corden.
Mackay said: “We all know the stereotypical idea of a stag or hen do usually involves drinking to excess but the reality is, more and more people don’t drink at all.
"We realised that, for those groups, they are terribly under served by options for stag and hen parties. That’s when the tee-total dos plan was hatched.”
Instead of the usual boozy pursuits, Taymouth Marina will offer its guests lochside sauna sessions and watersports.
With those looking for some extra fun being able to take on the Loch Slide Challenge, where the stag or hen will be expected to zip down a 20-foot water slide into Loch Tay, wearing fancy dress.
The group parties offer the stags and hens - and their guests - sauna sessions, watersports and detoxing smoothies at the lochside bar at the marina in Kenmore, Loch Tay.
The team say that in keeping with the health-conscious theme, saunas have long been known to "improve the immune system, improve cardiovascular performance and reduce stress".
A 2017 report from the Office for National Statistics showed the proportion of adults who say they drank alcohol was at the lowest level on record.
This trend has led to a rise in teetotalism, with 21 per cent of UK adults not drinking alcohol at all and lower levels of drinking among the rest of the population.
Despite the teetotal parties, Taymouth Marina does still offer alcoholic drinks at its lochside bar, which Angus says are for "those in the party who’re not quite ready to make the leap to teetotalism".
